What Makes a Complete Sentence
Before examining fragment types, it helps to understand what a complete sentence requires. Every complete sentence needs:
- A subject (who or what the sentence is about)
- A predicate with a finite main verb (what the subject does, is, or experiences)
- The ability to stand alone as a complete thought
If any of these is missing, the result is a fragment. For a full explanation of the grammar and a systematic approach to identifying fragments, see the guide on sentence fragments.
Type 1: Missing Subject Fragment
The sentence has a verb but no grammatical subject — no one or nothing performing the action.
Examples and fixes
- Fragment: Analyzed the data and wrote the report in three days.
- Fix: She analyzed the data and wrote the report in three days.
- Fragment: Submitted the proposal without reviewing it carefully.
- Fix: He submitted the proposal without reviewing it carefully.
- Fragment: Decided to postpone the launch until Q3.
- Fix: The team decided to postpone the launch until Q3.
Missing subject fragments are very common in rushed writing and are sometimes caused by a writer beginning a sentence with a past-tense verb that looks like a new clause but lacks a subject.
Type 2: Missing Verb Fragment
The sentence has a subject but no finite verb — a noun phrase, or a noun phrase modified by a participial phrase, with no predicate.
Examples and fixes
- Fragment: The new policy regarding remote work and flexible scheduling.
- Fix (attach): The new policy regarding remote work and flexible scheduling was announced at the all-hands meeting.
- Fix (expand): Management introduced the new policy regarding remote work and flexible scheduling.
- Fragment: An approach that addresses both the technical and organizational challenges.
- Fix: An approach that addresses both the technical and organizational challenges has not yet been identified.
- Fragment: The three reports submitted by the regional managers.
- Fix: The three reports submitted by the regional managers were reviewed before the meeting.
Type 3: Dependent Clause Fragment
The sentence contains both a subject and a verb, but it is introduced by a subordinating conjunction — making it a dependent clause that cannot stand alone. Common subordinating conjunctions that create this type: because, although, when, while, since, if, unless, after, before, even though, as, until, whenever.
Examples and fixes
- Fragment: Because the deadline was moved up.
- Fix (attach to following sentence): Because the deadline was moved up, the team had to work overtime.
- Fix (remove subordinator): The deadline was moved up.
- Fragment: Although the initial results were promising.
- Fix: Although the initial results were promising, the study required a larger sample.
- Fragment: When she finally reviewed the final version of the document.
- Fix: When she finally reviewed the final version of the document, she found several significant errors.
- Fragment: Unless additional funding is approved for the next fiscal year.
- Fix: Unless additional funding is approved for the next fiscal year, the project will not continue.
Type 4: Participial Phrase Fragment
The sentence consists of a participial phrase — a verb form (-ing or past participle) that modifies a noun — without a main clause attached. These often begin with having, being, knowing, considering, given, or any -ing or past participle.
Examples and fixes
- Fragment: Having reviewed all the available data.
- Fix (attach): Having reviewed all the available data, the analyst recommended a revised strategy.
- Fix (rewrite): The analyst reviewed all the available data and recommended a revised strategy.
- Fragment: Working late into the night to meet the deadline.
- Fix: The team was working late into the night to meet the deadline.
- Fragment: Given the complexity of the situation and the limited resources available.
- Fix: Given the complexity of the situation and the limited resources available, the committee tabled the proposal.
Type 5: Added-Detail Fragment
A complete sentence is followed by a punctuated fragment that adds details, often beginning with such as, for example, including, especially, like, also, and, or, but. These fragments are separated from the sentence they belong to by an incorrect period.
Examples and fixes
- Sentence + Fragment: The proposal covered several key areas. Such as budget, staffing, and timeline.
- Fix: The proposal covered several key areas, such as budget, staffing, and timeline.
- Sentence + Fragment: The team explored several options. For example, redesigning the onboarding process and reducing the approval steps.
- Fix: The team explored several options, for example redesigning the onboarding process and reducing the approval steps.
- Sentence + Fragment: She has experience in many areas. Including content strategy, brand development, and digital marketing.
- Fix: She has experience in many areas, including content strategy, brand development, and digital marketing.
Intentional Fragments
Not every fragment in published writing is an error. Writers sometimes use fragments deliberately for emphasis, pace, or stylistic effect:
- The answer was clear. No.
- She reached the top of the report. Nothing useful there, either.
- One more problem. Always one more problem.
Intentional fragments work when the writer controls them and the reader can feel the intent. In academic and professional writing, they are generally not appropriate. In journalism, marketing copy, and creative writing, they appear regularly and are accepted when used with purpose.
How to Check Your Writing for Fragments
- For every sentence, identify the subject and the finite verb. If either is missing, it is a fragment.
- For any sentence beginning with a subordinating conjunction, check that there is an independent clause either before or after it.
- For any sentence beginning with a participial phrase, check that it is attached to a main clause.
- For any sentence beginning with such as, including, for example, check whether it can stand alone. It almost certainly cannot — attach it to the preceding sentence.

Frequently Asked Questions
Can a sentence begin with "and" or "but" without being a fragment?
Yes. Sentences beginning with and or but are grammatically complete as long as they contain a subject and a finite verb. But the results were inconclusive. is a complete sentence, not a fragment. The concern about starting sentences with conjunctions is a stylistic preference, not a grammatical rule.
Is a single word ever a sentence?
Yes. Stop. is a complete sentence — it is an imperative with an implied subject (you). Fire!, Run., Help! are all grammatically complete imperative sentences with implied subjects. Single-word sentences are complete when the missing subject is clearly implied.
Are fragments acceptable in bullet points?
Yes. Bullets in slide decks, resumes, and reports frequently use sentence fragments — noun phrases or verb phrases without a complete independent clause structure. This is standard in those formats and not an error. The convention is that bullets are read in the context of the heading that introduces them. What matters is that all bullets in the same list use parallel structure, whether they are complete sentences or fragments.
